摘要: Porous Fe 2 O 3 particle was synthesized by the hydrothermal-calcination method and then used to activate peroxymonosulfate (PMS) for Rhodamine B (RhB) decolorization. Several analytical means such as X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and N 2 physisorption were used to determine the characteristics of the catalyst particles. The results of experiments indicated that the catalyst showed a high activity in decolorization of RhB in the presence of PMS. Several key parameters including initial pH …
